I'm overall satisfied with the HL-3140CW but there have been a few bumps in the road. Getting it activated on my network took longer than it should as the wizard didn't work after typing in my network key over and over again. I got it working by using the alternate USB method. Another issue I'm having is on a few occasions sending a document to print has caused it to start spitting out blank pages, after cancelling and resending the same document it prints out successfully. No big deal, but irksome. Otherwise the print quality is good. Won't have a opinion on toner usage until I get to time to replace them... hopefully not anytime soon.

Approximate toner cartridge yield in accordance with ISO/IEC 19798 (letter/A4). Drum yield is approx., and may vary by type of use.
